What Is Bandwidth?

This updated guide examines What Is Bandwidth? and organizes the essential facts, background, and practical takeaways in clear American English.

An Internet connection with a large bandwidth can move a large amount of data (say, video files) much faster than a low bandwidth Internet connection.

Bandwidth is usually expressed in bits per second, such as 60Mbps or 60Mbps, to explain the data transmission rate of 60 million bits per second.

Why is understanding bandwidth so important?

It's easy to see bandwidth as a technical term that doesn't really matter unless you want to test tech products or set up Internet hardware. In fact, understanding the meaning of bandwidth and how to apply it to your private network can help you adjust your settings for a faster Internet connection when needed.

You might be curious about bandwidth if your Internet connection is suddenly slower than other days. You may suspect that you should buy additional bandwidth or you don't get what you pay for.

You may also be buying a game console or using a video streaming service and need to understand exactly whether you can do so that will negatively affect the rest of the network. For most people, these two activities are the jobs that consume the largest bandwidth.

How many bandwidth do you have and need?

See the article: How to check the Internet speed or How to calculate the network bandwidth, transmission line on demand for help in determining the exact amount of bandwidth available. Websites check Internet speed often, but not always the best way to do it.

How much bandwidth you need depends on what you plan to do with your Internet connection. For most cases, the more bandwidth the better (but of course everything is constrained by the budget).

Depending on what you are using, you may receive official bandwidth recommendations, to know exactly what you will need to use that service optimally.

For example, if your Internet is running smoothly now but you plan to add movie streaming service in the near future, do some research on the service provider's website, to know the minimum amount of bandwidth proposed without interrupting the streaming.
